Wireless Technologies Overview Infrared technology is a wireless technology that operates over a short range and cannot penetrate through walls and other obstructions. Infrared Bluetooth is a wireless technology that permits wireless connection between electronic devices over short distances. Bluetooth Wi-Fi is a technology that permits wireless connection between electronic devices to share data or to access the Internet. Wi-Fi

Wireless Technologies – Infrared Infrared technology is based on the use of low-frequency light waves and has a short range of approximately 5 metres. The transmitter needs to be in a line of sight with the actual device that it controls, since it cannot penetrate through walls or other obstructions. Infrared technology is used in the gym for: Personal headsets – used by members to receive sound from the TV / entertainment systems from exercise machines Remote controllers – used by staff to set up TV and entertainment media in the gym File transfer communication – between mobile devices / smartphones Laptop peripherals – infrared mouse used by members to access their online account

Wireless Technologies – Infrared Benefits of using infrared technology are: High security as signal is short-range and directional so unlikely to be intercepted Low interference from other devices, so can be used for high-quality sound reproduction Low power usage so ideal for smartphones, headphones and remote controllers Limitations of using infrared technology are: Line of sight requires the transmitter and receiver to be directly aligned for communication Limited range so performance drops off above 5 metres Signal speed low compared to wired transmissions

Wireless Technologies – Bluetooth Bluetooth technology is mainly used to connect mobile electronic devices automatically once they are in range. It operates on low-power, short-wave radio signals within a range of approximately 10 metres. Bluetooth is used widely to connect peripherals such as mice or keyboards to smartphones or tablet computer devices. A Bluetooth device is a peer-to-peer paired connection, so it needs to be paired before it can commence communication. Note that once a device has been successfully paired it will automatically communicate if in range and both are switched on. iPad connected to a Bluetooth keyboard

Wireless Technologies – Bluetooth Uses Bluetooth can be used in the leisure centre in several ways, such as: Synchronisation of data between two devices. The iPad screenshot on the right shows details of the activity data from the Fitbit after the devices have been synchronised. Wearable heart-rate monitor is provided by the leisure centre; it communicates with the gym equipment using Bluetooth technology and displays the heart rate of the member. Linking peripherals to mobile devices. Members can link peripherals to their mobile devices to make them easier to use.

Wireless Technologies – Bluetooth Benefits of using Bluetooth technology are: Low power usage so ideal for battery-operated devices, such as: tablet computers, smartphones, mice, keyboards Automatic connection between Bluetooth devices once they have been paired Limitations of using Bluetooth technology are: Battery life can be reduced by switching OFF the device when data transmission is completed Signal speed lower than the speed that can be achieved with Wi-Fi and infrared transmissions

Wireless Technologies – Wi-Fi Wi-Fi is a technology that permits wireless connection between electronic devices to share data or to access the Internet. Connection from Progress Leisure LAN The Wi-Fi router shown in the schematic diagram above acts as a wireless access point and provides network access to a range of mobile devices. A LAN or local area network operates over a small area such as a single building or group of buildings.

Wireless Technologies – Wi-Fi Uses Wi-Fi can be used in the leisure centre in several ways, such as: Personal use – members can use the Wi-Fi to carry out tasks such as using social media, email or generally browsing the Internet. Member profile – members can log on and view their personal profile to get details of performance and attendance, and book classes. Progress Leisure website – members can browse the public area of the leisure centre website to find out details of forthcoming events and view gym equipment videos.

Wireless Technologies – Wi-Fi Benefits of using Wi-Fi technology are: Connections can be made without the need for wires. This makes a network more flexible due to changing requirements and is useful where it is not possible to fix wires. Limitations of using Wi-Fi technology are: The signal range is dependent upon distance from the router, and an obstruction such as thick walls can cause poor signal reception or a weak connection.
